Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a server node and a server. Background Technology

[0002] With the rise of big data, cloud computing, and artificial intelligence (AI), the computing demands on data centers and servers are increasing. To handle complex logical operations and different data types, server nodes typically integrate different types of functional units. Multiple server nodes are integrated within a server rack.

[0003] In related technologies, the server node chassis includes a first chassis and a second chassis, with the second chassis being smaller in volume than the first chassis. The first and second chassis can each house different types of functional units. When maintaining the functional units housed in the second chassis, both the first and second chassis need to be removed from the rack as a whole, resulting in a heavy chassis and inconvenient operation. Summary of the Invention

[0004] This application provides a server node and a server. Through structural optimization, the server node facilitates both the separate removal and maintenance of the second enclosure and the removal and maintenance of the first and second enclosures together relative to the server rack.

[0005] A first aspect of this application provides a server node, which includes a first housing, a second housing, and a first locking component. The first housing has a receiving cavity and includes an open first end. The second housing is located in the receiving cavity and can be inserted into or removed from the first housing from the first end. The first locking component is disposed between the sidewalls of the first housing and the sidewalls of the second housing, and is located near the first end of the first housing. The first locking component includes a linkage that can reciprocate to lock the first housing and the second housing, or to release the lock between the first housing and the second housing.

[0006] Using the above scheme, the second enclosure can be inserted into or pulled out of the first enclosure from the first end. The first and second enclosures can be locked or unlocked by operating the first locking component. During routine maintenance, the first and second enclosures can be locked together by using the first locking component, and the first and second enclosures of the server node can be pulled out together for maintenance. The second enclosure can be pulled out separately for maintenance by using the first locking component to unlock the first and second enclosures, making the operation convenient.

[0007] In practical applications, a server node includes a chassis, which includes a first enclosure and a second enclosure.

[0008] In one feasible solution, the server node includes a first functional unit and a second functional unit. The first functional unit is disposed in a first enclosure, and the second functional unit is disposed in a second enclosure. The first functional unit and the second functional unit are electrically connected.

[0009] For example, the first functional unit may include a central processing unit (CPU), a power supply module, and a hard disk module, etc.

[0010] For example, the second functional unit includes a graphics processing unit (GPU), etc.

[0011] In one feasible solution, the first lock component further includes a toggle member, a first lock frame, and a second lock frame. The first lock frame is fixedly mounted on the first housing, and the second lock frame is fixedly mounted on the outer side wall of the second housing. The toggle member is rotatably connected to the second housing, and a linkage member is connected to the toggle member. When the toggle member rotates, it can drive the linkage member to move to a first locked position or a first unlocked position. In the first locked position, the linkage member is simultaneously located within both the second lock frame and the first lock frame; in the first unlocked position, the linkage member is located outside the first lock frame. This first lock component has a relatively simple structure and is conducive to reducing space occupation. By rotating the toggle member of the first lock component, the linkage member can reciprocate between the first locked position and the first unlocked position, realizing the locking and unlocking of the first housing and the second housing.

[0012] In some examples, a partition plate is fixed inside the first enclosure, which divides the receiving cavity of the first enclosure into a first cavity and a second cavity along the height direction of the server node. The second enclosure is located in the first cavity or the second cavity, and a first locking frame is disposed on the partition plate.

[0013] In one feasible solution, one of the linkage and the actuating component has an elongated hole, and the linkage and the actuating component are connected by a connecting pin inserted into the elongated hole. This arrangement ensures that the linkage can reciprocate along the direction of insertion into or disengagement from the first locking frame under the action of the actuating component.

[0014] In one feasible solution, the middle part of the actuating element is rotatably connected to the second housing, one end of the actuating element is connected to the linkage element, and the other end of the actuating element has a plug-in portion for mating with tooling. This configuration facilitates user operation of the actuating element to switch the locked or unlocked state between the first and second housings.

[0015] In one feasible solution, the server node has a first locking component at both ends along a first direction, and the two first locking components are linked together; the first direction is perpendicular to the insertion / removal direction of the second enclosure relative to the first enclosure. This configuration helps to improve the locking force between the first and second enclosures, ensuring reliable locking between them.

[0016] In one feasible solution, the server node further includes a second locking component. The second locking component is mounted on the side wall of the first enclosure and positioned near its first end. The second locking component includes a locking lever located inside the first enclosure. The locking lever is rotatable relative to the first enclosure to lock the first enclosure to the rack where the server node is installed, or to release the lock between the first enclosure and the rack. This configuration improves the stability and reliability of the server node's installation within the rack. Simultaneously, when the second enclosure needs to be individually plugged in or unplugged, the first enclosure and rack can be locked, preventing accidental operation of the first enclosure and ensuring the safety and reliability of the second enclosure plugging / unplugging operations.

[0017] In one feasible solution, the first locking component and the second locking component are linked and configured such that: during the process of the first locking component locking the first enclosure and the second enclosure, force can be applied to the second locking component to release the lock between the first enclosure and the cabinet.

[0018] In one feasible solution, the first locking component and the second locking component are linked and configured such that when the linkage moves to the first locking position, it can apply an unlocking force to the first rod end of the locking rod, causing the locking rod to move in the direction of unlocking the first enclosure and cabinet. This configuration simplifies the operation process, and the first and second locking components can be compactly arranged, which helps to reduce the space occupied.

[0019] Specifically, the first locking component includes a linkage member capable of locking or unlocking the relative positions of the first enclosure and the second enclosure, and the second locking component includes a locking lever member capable of locking or unlocking the relative positions of the first enclosure and the server rack. When the linkage member moves in the direction capable of locking the first enclosure and the second enclosure, it causes the locking lever member to rotate in the direction capable of unlocking the first enclosure and the server rack, thereby achieving linkage control between the first locking component and the second locking component.

[0020] In some examples, the locking lever includes a first lever end and a second lever end opposite each other, with the first lever end located within the receiving cavity of the first housing and the second lever end extending out of the first housing from its first end. This arrangement facilitates operation of the second locking component by the user.

[0021] In one feasible solution, the locking lever is provided with ratchet teeth, and the first housing has a first through hole that engages with the ratchet teeth. The locking lever can rotate relative to the first housing to switch between a second locked position and a second unlocked position. In the second locked position, at least a portion of the ratchet teeth protrudes from the first through hole outside the first housing, and in the second unlocked position, the ratchet teeth are located inside the first housing. This second locking component has a simple structure and is conducive to reducing the space occupied.

[0022] In one feasible embodiment, the second lock component further includes a mounting base fixed to the inner side wall of the first housing. The lock rod is rotatably connected to the mounting base, and the mounting base has a second through hole communicating with the first through hole. This configuration allows the second lock component to be modularly designed, facilitating maintenance and assembly.

[0023] In one feasible embodiment, the second locking component further includes a fixing member and a resilient member. The fixing member is fixed to the mounting base, the locking lever is located between the fixing member and the mounting base, one end of the resilient member abuts against the fixing member, and the other end of the resilient member abuts against the locking lever; the resilient member enables the locking lever to remain in the second locked position. This configuration ensures effective locking of the first enclosure and cabinet.

[0024] In one feasible solution, the server node is equipped with second locking components at both ends along a first direction, the first direction being perpendicular to the insertion / removal direction of the second enclosure relative to the first enclosure. This configuration improves the locking effect between the first enclosure of the server node and the rack on which the server node is installed.

[0025] In one feasible solution, the server node further includes a pull-out aid, which is mounted on the end of the second housing near the first end. The pull-out aid is rotatable relative to the second housing and is configured to generate a force that moves the second housing along the insertion direction into the first housing when rotated in a first rotation direction, and to generate a force that moves the second housing along the removal direction from the first housing when rotated in a second rotation direction; the first rotation direction and the second rotation direction are opposite. Thus, the pull-out aid, in conjunction with the first locking component, can assist in the overall insertion and removal of the first and second housings, as well as the individual insertion and removal of the second housing, which helps reduce the space occupied on the front of the server node.

[0026] In one feasible solution, the pull-out assist component includes a wrench rotatably connected to a second housing, the wrench including a protruding arm; the first housing has a third through hole, through which the protruding arm can extend and engage with a limiting structure. This configuration provides the pull-out assist component with a leverage amplification effect, enabling it to meet larger insertion and extraction force requirements.

[0027] For example, the wrench may have only one protruding arm or more than two protruding arms. When the wrench has more than two protruding arms, each protruding arm of the wrench can sequentially engage with the limiting structure.

[0028] For example, the limiting structure is located on the cabinet wall of the rack where the server node is installed; or, the first enclosure of the server node is detachably connected to a limiting fixture, and the limiting structure is located on the limiting fixture.

[0029] A second aspect of this application provides a server, which includes a rack and a server node installed in the rack, wherein the server node is the aforementioned server node. Attached Figure Description

[0050] Servers are widely used in internet service providers, enterprise platforms, research institutions, and other scenarios for storage, computing, and networking needs. With the rapid development of the information and communication technology industry, server applications have expanded to the fields of cloud computing and artificial intelligence (AI), and the demand for computing resources to process and analyze massive amounts of data is growing daily.

[0051] A server may include one or more server nodes, with multiple server nodes housed within a server rack. To meet the ever-increasing computing power demands of servers, a single server node may integrate different types of functional units. Please refer to [reference needed]. Figure 1 , Figure 1 This is a schematic diagram of the server structure in an embodiment of this application.

[0052] like Figure 1 As shown, the server 1 includes a rack 2 and multiple server nodes 3, which are sequentially installed inside the rack 2. The server nodes 3 can be cooled by air or liquid cooling. One side wall of the server node 3 (usually the back side mentioned later) is provided with multiple connectors to connect and cooperate with multiple connectors in the rack 2 to realize power supply, signal transmission, or the flow of cooling medium.

[0053] When server node 3 integrates different types of functional units, the chassis of server node 3 can adopt a nested structure. Please refer to... Figure 2 , Figure 2 This is a schematic diagram of the server node structure in an embodiment of this application.

[0054] like Figure 2 As shown, server node 3 includes a chassis 100, which includes a first enclosure 10 and a second enclosure 20. The second enclosure 20 is located within the receiving cavity 10a of the first enclosure 10. That is, the second enclosure 20 is nested inside the first enclosure 10. The receiving cavity 10a of the first enclosure 10 is divided into two parts: one part is the space occupied by the second enclosure 20, and the remaining part is the space not occupied by the second enclosure 20. The space in the receiving cavity 10a of the first enclosure 10 not occupied by the second enclosure 20 can be used to install some types of functional units, and other types of functional units can be installed inside the second enclosure 20.

[0055] For the sake of simplicity, Figure 2 The diagram illustrates a first functional unit 71 installed inside a first housing 10, and a second functional unit 72 installed inside a second housing 20. The first functional unit 71 and the second functional unit 72 are electrically connected. This shortens the length of the communication cable between the first functional unit 71 and the second functional unit 72, thus improving communication speed. The positional relationship shown in the diagram is only an example; the relative positions of the first functional unit 71 and the second functional unit 72 can be set according to actual conditions. In some examples, the first functional unit 71 is electrically connected to a first connector 711, and the second functional unit 72 is electrically connected to a second connector 721. The first connector 711 and the second connector 721 are plugged in to achieve communication or power supply, etc.

[0056] In practical applications, server node 3 may need to be inserted into or removed from rack 2 as a whole, and the second enclosure 20 of server node 3 may need to be inserted into or removed from the first enclosure 10 separately.

[0057] Taking server node 3, which integrates a CPU (central processing unit) and a GPU (graphics processing unit), as an example, the GPU is installed in the second enclosure 20, while the CPU, memory, hard disk module, and power supply module are installed in the space not occupied by the second enclosure 20 within the first enclosure 10. That is, the first functional unit 71 includes the CPU, memory, hard disk module, and power supply module, while the second functional unit 72 includes the GPU. To meet the installation requirements of the CPU and GPU, the height of the first enclosure 10 can be 4U, and the height of the second enclosure 20 can be 3U. Here, 1U stands for 1 unit, and 1U = 44.45mm. In other application examples, the first enclosure 10 and the second enclosure 20 can also have other height dimensions.

[0058] In practical applications, the CPU, memory, hard disk module, and power supply module installed in the first enclosure 10 can be located above or below the second enclosure 20.

[0059] In one application example, the overall weight of server node 3, which integrates a CPU and GPU, can reach approximately 80 kilograms, with the second enclosure 20 and its internal functional units weighing approximately 50 kilograms. Therefore, the required insertion and removal force is significant when plugging or unplugging server node 3 as a whole or individually plugging or unplugging the second enclosure 20 and its internal functional units.

[0060] This application embodiment optimizes the structure of the chassis 100 for server node 3. By integrating auxiliary plug-in accessories onto the chassis 100, it facilitates both the overall plugging and unplugging of server node 3 and the plugging and unplugging of the second enclosure 20, while also avoiding excessive occupation of the front space of chassis 100. Here, the front of chassis 100 refers to the side of server node 3 facing outwards from the rack 2 or towards the user after it is placed in the rack 2 of server 1; correspondingly, the side of chassis 100 opposite to the front is the back, which is the side of server node 3 facing inwards from the rack 2 or away from the user after it is placed in the rack 2. Figure 1 and Figure 2 The label indicates that the front of the chassis 100 faces the negative Y direction, and the back faces the positive Y direction.

[0061] Please refer to this as well. Figure 3 and Figure 4 , Figure 3 and Figure 4 All of these are schematic diagrams of the chassis structure provided in the embodiments of this application, wherein, Figure 4 This is a partial structural diagram showing the second housing 20 not yet fully inserted into the first housing 10.

[0062] For ease of description, this paper defines three directions: the first direction X, the second direction Y, and the third direction Z. Referring to the structure shown in the diagram, the first direction X is the width of server node 3 or chassis 100, the second direction Y is the length (also called the depth) of server node 3 or chassis 100, and the third direction Z is the height of server node 3 or chassis 100. Figure 1 In the server 1 shown, the first direction X, the second direction Y and the third direction Z are also the width direction, length (depth) direction and height direction of the server 1, respectively, and multiple server nodes 3 are stacked in the height direction of the server 1.

[0063] like Figure 1 As shown, server node 3 is inserted into rack 2 of server 1 along the second direction Y. Figure 4 As shown, in the chassis 100 of server node 3, the second enclosure 20 is inserted into the first enclosure 10 along the second direction Y.

[0064] In this embodiment, the chassis 100 of server node 3 includes a first chassis 10, a second chassis 20, and a first locking component 40.

[0065] The first housing 10 has a receiving cavity 10a. The first housing 10 includes a first end 101 and a second end 102 opposite each other in the second direction Y.

[0066] The second housing 20 is located in the receiving cavity 10a of the first housing 10, and the second housing 20 includes a third end 201 and a fourth end 202 opposite to each other in the second direction Y.

[0067] When the second housing 20 is inserted into the first housing 10, the third end 201 of the second housing 20 is adjacent to the first end 101 of the first housing 10, and the fourth end 202 of the second housing 20 is adjacent to the second end 102 of the first housing 10.

[0068] The chassis 100 can be inserted into the rack 2 along the direction from the first end 101 to the second end 102. It can be understood that the first end 101 of the first chassis 10 is the front end of the chassis 100, and the second end 102 of the first chassis 10 is the back end of the chassis 100.

[0069] In the illustrated example, the insertion direction of the second housing 20 relative to the first housing 10 is from the first end 101 to the second end 102, or from the third end 201 to the fourth end 202; the removal direction of the second housing 20 relative to the first housing 10 is from the second end 102 to the first end 101, or from the fourth end 202 to the third end 201. In other words, the insertion and removal direction of the second housing 20 relative to the first housing 10 is the second direction Y.

[0070] A first locking component 40 is disposed between the first housing 10 and the second housing 20. The first locking component 40 is configured to lock the first housing 10 and the second housing 20, or to unlock the first housing 10 and the second housing 20. The first locking component 40 has a first locking position for locking the first housing 10 and the second housing 20, and a first unlocking position for unlocking the first housing 10 and the second housing 20.

[0071] After the above settings are configured, the first enclosure 10 and the second enclosure 20 of the chassis 100 can be connected together or separated by the operation of the first locking component 40, thereby achieving locking or unlocking between the two. During routine maintenance, the first enclosure 10 and the second enclosure 20 can be locked by using the first locking component 40, and the first enclosure 10 and the second enclosure 20 can be pulled out together for maintenance. The second enclosure 20 can be pulled out separately for maintenance by using the first locking component 40 to unlock the first enclosure 10 and the second enclosure 20. The operation is convenient.

[0072] In this embodiment, the chassis 100 of server node 3 further includes a pull-out aid 30, which is rotatably connected to the second housing 20. The pull-out aid 30 is configured to generate a force that moves the second housing 20 along the insertion direction of the first housing 10 when rotated in a first rotation direction, and to generate a force that moves the second housing 20 along the pull-out direction of the first housing 10 when rotated in a second rotation direction; the first rotation direction is opposite to the second rotation direction. Thus, in conjunction with the first locking component 40, the pull-out aid 30 can provide force for the individual insertion and removal of the second housing 20, or for the insertion and removal of the first housing 10 and the second housing 20 as a whole, avoiding the need to set pull-out aid structures on both the first housing 10 and the second housing 20, which helps to reduce the space occupied on the front of the chassis 100.

[0073] Using the above scheme, the insertion and removal operation of the second housing 20 relative to the first housing 10 is as follows:

[0074] When the second housing 20 is inserted into the first housing 10, the pull-out aid 30 installed on the second housing 20 can be used to rotate the pull-out aid 30 in the first rotation direction to generate a force acting on the second housing 20 in the insertion direction, facilitating the insertion of the second housing 20 into the first housing 10. After the second housing 20 is inserted into the first housing 10, the first housing 10 and the second housing 20 can be locked by the first locking member 40 to restrict the relative positions of the first housing 10 and the second housing 20.

[0075] When the second housing 20 is pulled out of the first housing 10, the first locking component 40 is used to release the lock between the first housing 10 and the second housing 20. The auxiliary pulling component 30 installed on the second housing 20 can be used to rotate the auxiliary pulling component 30 in the second rotation direction to generate a force acting on the second housing 20 in the pulling direction, so as to facilitate the second housing 20 to be pulled out of the first housing 10.

[0076] Using the above method, the plugging and unplugging operation of chassis 100 relative to rack 2 of server 1 is as follows:

[0077] When the chassis 100 is operated as a whole, the first housing 10 and the second housing 20 can be locked by the first locking component 40 to restrict their relative positions.

[0078] When inserting the chassis 100 into the rack 2, the pull-out aid 30 installed on the second housing 20 can be used to rotate the pull-out aid 30 in the first rotation direction, thereby generating a force acting on the second housing 20 in the insertion direction. Because the second housing 20 and the first housing 10 are locked together, the force generated by the pull-out aid 30 actually acts on both the first housing 10 and the second housing 20, facilitating the insertion of the chassis 100 into the rack 2.

[0079] When removing the chassis 100 from the rack 2, the pull-out aid 30 installed on the second housing 20 can be used to rotate the pull-out aid 30 in the second rotation direction, thereby generating a force acting on the second housing 20 in the pull-out direction. Because the second housing 20 and the first housing 10 are locked together, the force generated by the pull-out aid 30 actually acts on the first housing 10 and the second housing 20, facilitating the removal of the chassis 100 from the rack 2.

[0080] The chassis 100 provided in this embodiment only needs to be equipped with an auxiliary component 30 on the second housing 20, which, together with the first locking component 40 between the second housing 20 and the first housing 10, allows for convenient plugging and unplugging of the second housing 20 and the chassis 100 as a whole, which helps to reduce the space occupied on the front of the chassis 100.

[0081] In a specific implementation, the outer contour dimensions of the second box 20 are smaller than those of the first box 10, so that the second box 20 can be located inside the first box 10.

[0082] In some examples, such as Figure 2 As shown, the length of the second housing 20 can be less than the length of the first housing 10. After the second housing 20 is inserted into the first housing 10, there is still space between the fourth end 202 of the second housing 20 and the second end 102 of the first housing 10. This space is part of the receiving cavity 10a and can be used to install functional units such as power modules.

[0083] The first housing 10 may include a first top wall 110, a first bottom wall 120, a first side wall 130, and a second side wall 140. The first top wall 110 and the first bottom wall 120 are arranged opposite each other in the third direction Z, and the first side wall 130 and the second side wall 140 are arranged opposite each other in the first direction X. The first end 101 of the first housing 10 is an open end or an exposed end, and the second housing 20 can be inserted into the first housing 10 from the first end 101 or pulled out from the first housing 10 from the first end 101.

[0084] The second box 20 may include a second box top wall 210, a second box bottom wall 220, a third box side wall 230, a fourth box side wall 240 and a fifth box side wall 250. The second box top wall 210 and the second box bottom wall 220 are arranged opposite each other in the third direction Z, the third box side wall 230 and the fourth box side wall 240 are arranged opposite each other in the first direction X, and the fifth box side wall 250 is located at the third end 201 of the second box 20.

[0085] The first side wall 130 of the first box 10 and the third side wall 230 of the second box 20 are located at the same end, and the second side wall 140 of the first box 10 and the fourth side wall 240 of the second box 20 are located at the same end.

[0086] In other embodiments, the structures of the first housing 10 and the second housing 20 may also be in other forms, not limited to those described above. For example, the second housing 20 may not have a second top wall 210.

[0087] In practice, the pull-out aid 30 is installed at the third end 201 of the second housing 20, that is, on the front side near the housing 100, so as to facilitate the operation of the pull-out aid 30.

[0088] The pull-out aid 30 can be positioned close to the third side wall 230 and / or the fourth side wall 240 of the chassis 100 to reduce the space occupied on the front of the chassis 100.

[0089] In some examples, pull-out aids 30 are provided at both ends along the first direction X of the second housing 20 so that the forces applied to the second housing 20 or the locked first housing 10 and the second housing 20 are balanced.

[0090] In specific implementation, the first locking component 40 is installed close to the front side of the chassis 100 for easy operation. The first locking component 40 is located between the side wall of the first chassis 10 and the side wall of the second chassis 20, and is located close to the first end 101 of the first chassis 10.

[0091] by Figure 3 and Figure 4As shown, the first locking component 40 may be disposed between the first side wall 130 of the first box 10 and the third side wall 230 of the second box 20, and / or, the first locking component 40 may be disposed between the second side wall 140 of the first box 10 and the fourth side wall 240 of the second box 20.

[0092] In some examples, a first locking component 40 is provided at both ends along the first direction X of the chassis 100 so that the locking force between the first housing 10 and the second housing 20 is balanced.

[0093] In this embodiment, the chassis 100 further includes a second locking component 50, which is mounted on the first enclosure 10. The second locking component 50 is configured to lock the first enclosure 10 and the rack 2, or to unlock the lock between the first enclosure 10 and the rack 2. In other words, the second locking component 50 has a second locking position for locking the first enclosure 10 and the rack 2, and a second unlocking position for unlocking the lock between the first enclosure 10 and the rack 2.

[0094] With this configuration, after the chassis 100 is installed in the rack 2 of the server 1, the first chassis 10 and the rack 2 can be locked by the second locking component 50, restricting their relative positions. Combining the locking of the first chassis 10 and the second chassis 20 by the first locking component 40 improves the stability and reliability of the chassis 100 installed in the rack 2. Simultaneously, when the second chassis 20 needs to be individually plugged in or unplugged, locking the first chassis 10 to the rack 2 by the second locking component 50 ensures the safety and reliability of the plugging / unplugging operation of the second chassis 20.

[0095] In a specific implementation, the second locking component 50 is installed at the first end 101 of the first housing 10, that is, on the front side near the housing 100, so as to facilitate the operation of the second locking component 50.

[0096] The second locking component 50 can be located close to the first enclosure side wall 130 or the second enclosure side wall 140 to reduce the space occupied on the front of the enclosure 100.

[0097] In some examples, second locking components 50 are provided at both ends along the first direction X of the first enclosure 10 to balance the locking force between the first enclosure 10 and the cabinet 2. The second locking components 50 can be installed on the side wall of the first enclosure 10 to... Figure 3 and Figure 4 As shown, the second locking component 50 is installed on the first box side wall 130, and / or the second locking component 50 is installed on the second box side wall 140.

[0098] Figure 3 and Figure 4In the example shown, the second box 20 is provided with a first locking component 40 at both ends in the first direction X, and the first box 10 is provided with a second locking component 50 at both ends in the first direction X. In the figure, the first locking component 40 near the third box side wall 230 is in the first unlocked position, the first locking component 40 near the fourth box side wall 240 is in the first locked position, the second locking component 50 near the first box side wall 130 is in the second locked position, and the second locking component 50 near the second box side wall 140 is in the second unlocked position.

[0099] The specific structure of the first locking component 40 is described below.

[0100] Please refer to this as well. Figures 5 to 8 , Figure 5 This is a partial enlarged view of the location of the first locking component on the side of the second sidewall of the chassis in this embodiment of the application. Figure 6 This is a partial enlarged view of the location of the first lock component on the side of the fourth box in the embodiment of this application. Figure 7 This is a partial enlarged view of the location of the first locking component on the side of the third box, as described in this embodiment of the application. Figure 8 for Figure 7 The diagram shows an exploded view of the first locking component. To clearly illustrate the structure of the first locking component, Figure 5 Only the structure of the first lock component 40, the first housing 10, and the second housing 20 is shown in the diagram. Figures 6 to 8 Only the structure of the first lock component 40 and the second housing 20 is shown in the diagram. Figure 5 and Figure 6 The first locking component 40 is in the first locked position. Figure 7 and Figure 8 The first locking component 40 is in the first unlocked position.

[0101] In this embodiment, the first locking component 40 includes a linkage 42, which can reciprocate to lock the first housing 10 and the second housing 20, or release the lock between the first housing 10 and the second housing 20.

[0102] In a specific implementation, the first lock component 40 also includes a toggle member 41, a first lock frame 43, and a second lock frame 44.

[0103] The first lock frame 43 is fixedly installed on the first housing 10. In some examples, the first lock frame 43 can be integrally formed with the first housing 10. In other examples, the first lock frame 43 can be formed separately and then fixedly connected to the first housing 10.

[0104] The second lock frame 44 is fixedly installed on the outer side wall of the second housing 20. In some examples, the second lock frame 44 can be integrally formed with the second housing 20. In other examples, the second lock frame 44 can be formed separately and then fixedly connected to the second housing 20.

[0105] The actuating element 41 is rotatably connected to the second housing 20, and the linkage element 42 is connected to the actuating element 41. When the actuating element 41 rotates, it can move the linkage element 42 to a first locked position that is simultaneously located within the second lock frame 44 and the first lock frame 43, or it can move the linkage element 42 to a first unlocked position located outside the first lock frame 43. The first lock frame 43 and the second lock frame 44 are arranged in the direction of movement of the linkage element 42.

[0106] In some examples, the movement direction of the linkage 42 is a straight line, specifically along the third direction Z. The first lock frame 43 and the second lock frame 44 are arranged in the third direction Z, with the first lock frame 43 located above the second lock frame 44. This arrangement helps to reduce the space occupied by the first lock component 40 and also facilitates the arrangement of the first lock frame 43 and the second lock frame 44.

[0107] In the specific implementation, at the first unlock position, part of the linkage 42 is inserted into the second lock frame 44. In this way, the linkage 42 can be limited.

[0108] In a specific implementation, at least one of the actuating member 41 and the linkage member 42 is provided with an elongated hole 422, and the linkage member 42 and the actuating member 41 are connected by a connecting pin 46 inserted into the elongated hole 422. In this way, it can be ensured that the linkage member 42 can reciprocate along the direction in which it can be inserted into or disengaged from the first locking frame 43 under the action of the actuating member 41, and the relevant configuration of the elongated hole 422 can ensure that the movement direction of the linkage member 42 is linear.

[0109] The actuating member 41 is rotatably connected to the third box side wall 230 or the fourth box side wall 240 of the second box 20. The rotation center line of the actuating member 41 is parallel to the first direction X, so that the rotation of the actuating member 41 can drive the linkage member 42 to move in the third direction Z.

[0110] like Figure 5 As shown, taking the first locking component 40 installed on the fourth side wall 240 of the second box 20 as an example, the second box 20 is located behind the first box 10, and the first locking component 40 is located in the space formed between the fourth side wall 240 of the second box 20 and the second side wall 140 of the first box 10.

[0111] The first locking component 40 installed on the third side wall 230 of the second housing 20 is located in the space formed between the third side wall 230 of the second housing 20 and the first side wall 130 of the first housing 10.

[0112] The actuating element 41 can be in the form of a strip or a rod. The middle part of the actuating element 41 is rotatably connected to the second housing 20. One end of the actuating element 41 is connected to the linkage element 42, and the other end of the actuating element 41 has a plug-in portion 412 for mating with a tool. In practical applications, a tool can be plugged into the plug-in portion 412 of the actuating element 41 to apply force to the actuating element 41, causing it to rotate and drive the linkage element 42 to move.

[0113] In the actual configuration, one end of the actuating member 41 with the insertion part 412 is close to the third end 201 of the second housing 20, while the end of the actuating member 41 connected to the linkage member 42 is relatively far away from the third end 201 of the second housing 20. Thus, after assembly, the insertion part 412 of the actuating member 41 is close to the front side of the housing 100, which facilitates applying force to the actuating member 41.

[0114] Meanwhile, the end of the toggle member 41 with the plug portion 412 does not extend beyond the third end 201 of the second housing 20. After assembly, the first locking component 40 occupies the dimension of the housing 100 in the second direction Y.

[0115] For example, the insertion portion 412 of the toggle member 41 can be in the form of a socket or a notch.

[0116] like Figure 8 As shown, the end of the actuating member 41 connected to the linkage member 42 has a first connecting hole 411, and the end of the linkage member 42 connected to the actuating member 41 has a second connecting hole 422. A connecting pin 46 passes through the first connecting hole 411 and the second connecting hole 422 to connect the linkage member 42 and the actuating member 41. The second connecting hole 422 is an elongated hole, and its length extends along the second direction Y. When force is applied to the actuating member 41 to make it rotate, the movement of the connecting pin 46 in the elongated hole restricts the rotation of the linkage member 42 and causes the linkage member 42 to move along the third direction Z.

[0117] In other embodiments, the first connecting hole 411 of the toggle member 41 may also be configured as an elongated hole.

[0118] like Figure 8 As shown, taking the first locking component 40 installed on the third box side wall 230 of the second box 20 as an example, a protrusion 260 can be provided on the third box side wall 230. The first locking component 40 includes a first rotating shaft 45, which passes through the actuating member 41 and is inserted into the protrusion 260, so that the actuating member 41 can rotate around the first rotating shaft 45.

[0119] like Figure 7 and Figure 8As shown, the first locking component 40 is in the first unlocked position, and the actuating component 41 is in a position extending approximately along the second direction Y. At this time, the linkage component 42 is inserted into the second locking frame 44, and the linkage component 42 can partially extend out of the second locking frame 44, but the extended part has no cooperation with the first locking frame 43. When it is necessary to lock the first housing 10 and the second housing 20, force can be applied to the end where the insertion part 412 of the actuating component 41 is located by the tooling, so that the end where the insertion part 412 of the actuating component 41 is located rotates downward, thereby rotating the end of the actuating component 41 connected to the linkage component 42 upward, driving the linkage component 42 to move upward, so that the linkage component 42 can be inserted into the first locking frame 43 to be in the first locked position, such as... Figure 5 and Figure 6 As shown.

[0120] In a specific implementation, the first locking component 40 may be provided with a stop structure to restrict the position of the toggle member 41 or the linkage member 42, so that the linkage member 42 can be held in the first locked position or the first unlocked position.

[0121] In some examples, the stop structure can be a damping structure or a fixed-point limiting mechanism. The damping structure is disposed between the actuating member 41 and the first rotating shaft 45, so that the actuating member 41 can be held in the first unlocked position or in the first locked position. The damping structure or fixed-point limiting mechanism can be implemented by those skilled in the art based on conventional technology, and will not be described in detail here.

[0122] In other examples, the stop structure may include a first limiting part and a second limiting part. The first limiting part is used to hold the actuating member 41 in the first unlocked position, and the second limiting part is used to hold the linkage member 42 in the first locked position. The first limiting part may be a stop block located below the actuating member 41, which may be fixed to the side wall of the second housing 20. When the actuating member 41 rotates to the first unlocked position, it is restricted by the stop block and cannot continue to rotate, thus remaining in the first locked position. Figure 7 The first unlocking position is shown. The second limiting part can be a floating spring structure, etc., disposed between the second lock frame 44 and the linkage member 42. After the linkage member 42 moves to the first locking position, the floating spring structure can apply force to the linkage member 42 to keep it in the first locking position. The floating spring structure can be implemented by those skilled in the art based on conventional technology, and will not be described in detail here.

[0123] To facilitate the installation of the first lock frame 43 in the first housing 10, a partition can be provided within the receiving cavity 10a of the first housing 10. Please refer to the following: Figure 9 , Figure 9 A partial enlarged view of the first housing near the first end is shown.

[0124] like Figure 9As shown, the partition inside the first housing 10 includes a partition plate 150. The partition plate 150 is arranged parallel to the top wall 110 and the bottom wall 120 of the first housing, and is located between the top wall 110 and the bottom wall 120 of the first housing. The partition plate 150 divides the receiving cavity 10a of the first housing 10 into a first cavity 11a and a second cavity 12a in the third direction Z. The first cavity 11a is located below the second cavity 12a. The second housing 20 is located inside the first cavity 11a. The height of the first cavity 11a in the third direction Z is adapted to the height of the second housing 20.

[0125] The partition plate 150 is connected to the first box side wall 130 and the second box side wall 140 on its two sides in the first direction X, respectively. Figure 5 and Figure 9 The aforementioned first lock frame 43 can be fixed on the partition plate 150. Both the first lock frame 43 and the second lock frame 44 have through holes into which the linkage member 42 can be inserted. The first lock frame 43 and the second lock frame 44 are positioned correspondingly in the third direction Z, that is, the through hole of the first lock frame 43 is connected to the through hole of the second lock frame 44.

[0126] In addition to facilitating the installation of the first lock frame 43, the partition plate 150 also provides a mounting base for functional units installed in the second cavity 12a of the first housing 10. For example, a hard drive module installed in the first housing 10 can be supported by the partition plate 150.

[0127] The partition provided inside the first housing 10 may also include a side partition 160. The side partition 160 is arranged parallel to the side wall 130 of the first housing or the side wall 140 of the second housing. The side partition 160 is located in the second cavity 12a, and the top side of the side partition 160 is connected to the partition plate 150, and the bottom side is connected to the bottom wall 120 of the first housing. There may be two side partitions 160, one side partition 160 is located near the side wall 130 of the first housing, and the other side partition 160 is located near the side wall 140 of the second housing. The arrangement of the two side partitions 160 does not affect the nesting and cooperation between the second housing 20 and the first housing 10. After the second housing 20 is inserted into the first housing 10, the two side partitions 160 are located on the outside of the third housing side wall 230 and the fourth housing side wall 240 of the second housing 20, respectively. In other words, the space for accommodating the second box 20 is enclosed between the two side partitions 160, the partition plate 150 and the bottom wall 120 of the first box, and the side partitions 160 are equivalent to further dividing the first cavity 11a.

[0128] This configuration separates the second housing 20 from the functional units installed in the first housing 10, preventing interference with the functional units in the first housing 10 when the second housing 20 is plugged in or unplugged relative to the first housing 10.

[0129] Figure 9Due to the viewing angle, only the side partition 160 near the side wall 130 of the first box 10 can be seen.

[0130] In a specific implementation, the dimension of the side partition 160 in the second direction Y is smaller than the length of the first box side wall 130 or the second box side wall 140. On the side where the first end 101 of the first box 10 is located, there is a clearance distance between the end of the side partition 160 and the end of the first box side wall 130 or the second box side wall 140. This clearance distance is used to avoid the first locking component 40 so that the second box 20 is located behind the first box 10, and the linkage 42 of the first locking component 40 can cooperate with the first lock frame 43.

[0131] In other embodiments, the partition plate 150 or the side partition plate 160 may not be provided inside the first box 10, and the first locking frame 43 may be fixed to the inside of the first box side wall 130 or the second box side wall 140; the second box top wall 210 of the second box 20 may serve as the mounting base for functional units such as hard disk modules.

[0132] In some embodiments, when the chassis 100 is provided with first locking components 40 at both ends in the first direction, the two first locking components 40 can also be linked together. For example, the two toggle members 41 can be connected by a linkage rod, so that when one toggle member 41 is operated, the other toggle member 41 moves accordingly.

[0133] The specific structure of the second locking component 50 is described below.

[0134] Please refer to this as well. Figures 10 to 16 , Figure 10 This is a partial enlarged view of the first housing at the location of the second lock component on the side where the first housing sidewall is located, according to an embodiment of this application. Figure 11 and Figure 12 The diagrams show the structure of the second lock component from two different perspectives. Figure 13 and Figure 14 Exploded schematic diagrams of the second lock component are shown from two different perspectives. Figure 15 A partial sectional view of the first housing at the location of the second locking component on the side where the first housing sidewall is located is shown. Figure 16 A partial cross-sectional view of the first housing at the location of the second locking component on the side where the second housing sidewall is located is shown. Figure 10 , Figure 11 and Figure 15 The second locking component 50 is in the second locked position. Figure 16 The second locking component 50 is in the second unlocked position.

[0135] In this embodiment, the first box side wall 130 and the second box side wall 140 of the first box 10 are both equipped with a second locking component 50.

[0136] The second locking component 50 includes a locking rod 51, which is located inside the first enclosure 10. The locking rod 51 can rotate relative to the first enclosure 10 to lock the first enclosure 10 and the rack 2 on which the server node 1 is installed, or to release the lock between the first enclosure 10 and the rack 2.

[0137] In a specific implementation, the locking rod 51 is provided with a ratchet 511, and the first housing 11 has a first through hole 171 that cooperates with the ratchet 511.

[0138] The first box body 11 has a first through hole 171 on the first box side wall 130 and the second box side wall 140, which respectively cooperate with the locking rod 51 of the two second locking components 50.

[0139] The locking lever 51 can rotate relative to the first housing 10 to switch between a second locked position and a second unlocked position. In the second locked position, at least a portion of the ratchet 511 extends out of the first housing 10 from the first through hole 171. In the second unlocked position, the ratchet 511 is located inside the first housing 10.

[0140] In the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the first housing 10. For the second lock component 50 installed on the first housing side wall 130, in the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the first housing side wall 130. For the second lock component 50 installed on the second housing side wall 140, in the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the second housing side wall 140.

[0141] The cabinet 2, on which the chassis 100 is installed, is provided with a structure that engages with the ratchet 511 of the locking rod 51, so as to realize the locking of the first enclosure 10 and the cabinet 2 by the second locking component 50.

[0142] In practice, after the chassis 100 is installed in the cabinet 2, the cabinet 2 has a first cabinet wall corresponding to the first side wall 130 of the first chassis 10, and a second cabinet wall corresponding to the second side wall 140 of the first chassis 10. Recessed portions are provided on both the first and second cabinet walls. The second locking component 50 is in the second locked position, and the ratchet 511 of the locking lever 51 extends from the first through hole 171 and can be inserted into the recessed portion of the cabinet 2 to lock the first chassis 10 and the cabinet 2.

[0143] In this embodiment, the second locking component 50 may further include a mounting base 52, which is fixedly connected to the first housing 10. The mounting base 52 is fixed to the inner side wall of the first housing 10, and the locking rod 51 is rotatably connected to the mounting base 52. The mounting base 52 has a second through hole 523, which communicates with the first through hole 171 of the first housing 10, so that when the locking rod 51 rotates, the ratchet 511 of the locking rod 51 can extend out of the first housing 10 from the second through hole 523 and the first through hole 171. It can be understood that after the mounting base 52 is fixed to the first housing 10, the position of the second through hole 523 corresponds to the position of the first through hole 171. This facilitates the assembly of the locking rod 51.

[0144] In this embodiment, the second locking component 50 further includes a fixing member 54 and an elastic member 55. The fixing member 54 is fixed to the mounting base 52, and the locking rod 51 is located between the fixing member 54 and the mounting base 52. One end of the elastic member 55 abuts against the fixing member 54, and the other end of the elastic member 55 abuts against the locking rod 51. The elastic member 55 can keep the locking rod 51 in the second locking position.

[0145] In application, the locking lever 51 is in the second locked position. When an external force is applied to the locking lever 51, it rotates towards the second unlocked position. During this rotation, the elastic element 5 can accumulate elastic deformation energy. After the external force applied to the locking lever 51 is removed, the locking lever 51 can rotate towards the second locked position under the action of the elastic deformation energy of the elastic element 5.

[0146] This configuration ensures the locking effect of the second locking component 50 on the first enclosure 10 and the cabinet 2.

[0147] The second locking component 50 is mounted on the first housing 10 via the mounting base 52. Thus, the second locking component 50 is a modular structure, which facilitates assembly and maintenance.

[0148] The fixing member 54 is fixedly connected to the mounting base 52, and the locking rod 51 is located between the fixing member 54 and the mounting base 52. This allows for the placement of an elastic member 55 between the locking rod 51 and the fixing member 54, and also limits the rotation range of the locking rod 51, preventing the locking rod 51 from affecting the functional units installed in the first housing 10.

[0149] For example, the fastener 54 and the mounting base 52 can be detachably connected using fasteners such as screws.

[0150] The mounting base 52 and the first housing 10 can be detachably connected to facilitate maintenance or replacement of the second locking component 50. For example, the mounting base 52 may have a third connecting hole 521, and the first housing 10 may have a first mounting hole 181 corresponding to the position of the third connecting hole 521. The mounting base 52 and the first housing 10 are fixedly connected by screws or other fasteners passing through the first mounting hole 181 and the third connecting hole 521. The first mounting hole 181 is located on the first side wall 130 or the second side wall 140 of the first housing 10.

[0151] The locking rod 51 can be rotatably connected to the mounting base 52 via the second pivot 53. The locking rod 51 can be in the form of a strip or a rod, and the locking rod 51 includes a first rod end 5101 and a second rod end 5102 opposite to each other.

[0152] The rotation center line of the locking rod 51, that is, the axial direction of the second rotating shaft 53, is parallel to the third direction Z. The locking rod 51 rotates in the plane constructed by the first direction X and the second direction Y.

[0153] In some examples, the second pivot 53 is located between the first rod end 5101 and the second rod end 5102, and is positioned closer to the first rod end 5101. The ratchet 511 of the locking rod 51 is positioned relative to the second pivot 53, closer to the second rod end 5102. Applying force to either the first rod end 5101 or the second rod end 5102 will cause the locking rod 51 to rotate around the second pivot 53.

[0154] In some examples, the first housing 10 includes an open end, which is the first end 101 of the first housing 10, and the second locking component 50 is located near the open end of the first housing 10 to facilitate operation of the second locking component 50.

[0155] The first end 5101 of the locking rod 51 is located inside the receiving cavity 10a of the first housing 10, and the second end 5102 can extend out of the first housing 10 from the opening end of the first housing 10, such as... Figure 10 As shown, this allows the user to apply force to the second rod end 5102.

[0156] With the locking rod 51 mounted on the mounting base 52, the mounting base 52 may be provided with an opening 524. The second rod end 5102 of the locking rod 51 corresponds to the position of the opening 524. The end of the mounting base 52 with the opening 524 extends out of the first housing 10, so that the second rod end 5102 is exposed, making it convenient for the user to apply force to the second rod end 5102.

[0157] In a specific implementation, at least one of the fixing member 54 and the locking rod member 51 is provided with a positioning structure to limit the position of the elastic member 55 and prevent the elastic member 55 from shifting and failing to function.

[0158] In some examples, the positioning structure includes a positioning post 541 provided on the fixing member 54 and a positioning hole 513 provided on the locking rod member 51. One end of the elastic member 55 is sleeved on the positioning post 541, and the other end of the elastic member 55 is inserted into the positioning hole 513, such as... Figure 13 and Figure 15 .

[0159] The positioning hole 513 of the locking rod 51 can be set at the location of the ratchet 511. The thickness of the ratchet 511 is relatively large, which facilitates the setting of the positioning hole 513.

[0160] In other examples, the positioning structure may include two positioning posts, which are respectively disposed on the locking rod 51 and the fixing member 54, and the two ends of the elastic member 55 are respectively sleeved on the two positioning posts.

[0161] In other examples, the positioning structure may include two positioning holes, which are respectively located on the locking rod 51 and the fixing member 54, and the two ends of the elastic member 55 are respectively inserted into the two positioning holes.

[0162] In other examples, the positioning structure may consist only of positioning pins or positioning holes provided on the locking rod 51 or the fixing member 54.

[0163] For example, the elastic element 55 can be a spring.

[0164] Please refer to this as well. Figure 17 and Figure 18 , Figure 17 This is a partial cross-sectional view of the positions of the first and second locking components on the side where the first and third box sidewalls are located, as described in the embodiment of this application. Figure 18 This is a partial cross-sectional view of the positions of the first and second locking components on the side where the second and fourth box sidewalls are located, according to an embodiment of this application. Figure 17 The first locking component 40 is in the first unlocked position, and the second locking component 50 is in the second locked position. Figure 18 The first locking component 40 is in the first locked position, and the second locking component 50 is in the second unlocked position.

[0165] In this embodiment, the first locking component 40 and the second locking component 50 can be linked together and configured such that: during the process of locking the first enclosure 10 and the second enclosure 20, the first locking component 40 can apply force to the second locking component 50 to release the lock between the first enclosure 10 and the cabinet 2.

[0166] In practical applications, when the chassis 100 needs to be removed from the cabinet 2, only the first locking component 40 needs to be operated to simultaneously unlock the first chassis 10 from the cabinet 2 and lock the first chassis 10 and the second chassis 20. The operation is simple.

[0167] Because of the elastic element 55 of the second locking component 50, when the first locking component 40 switches to the first unlocking position to release the first housing 10 and the second housing 20 from locking, the force applied by the first locking component 40 to the second locking component 50 disappears. At this time, the second locking component 50 can be reset to the second locking position under the action of the elastic element 55.

[0168] In specific implementation, during the insertion of the linkage 42 of the first lock component 40 into the first lock frame 43, that is, when the linkage 42 moves in the direction of locking the first housing 10 and the second housing 20, as... Figure 6 The locking lever 51 of the second locking component 50 can apply an unlocking force to rotate the locking lever 51 toward the second unlocking position, such as... Figure 16 and Figure 18 .

[0169] The linkage 42 can apply force to the first rod end 5101 of the locking rod 51. The first rod end 5101 of the locking rod 51 is located above the first lock frame 43, so that when the linkage 42 is inserted into the first lock frame 43, force is applied to the first rod end 5101, which can be combined. Figure 6 , Figure 16 and Figure 18 understand.

[0170] The end of the linkage 42 that is inserted into the first lock frame 43 may be provided with a first wedge-shaped surface 421, such as... Figure 6 The first end 5101 of the locking rod 51 is provided with a second wedge-shaped surface 512, such as... Figure 12 During the process of inserting the linkage 42 into the first lock frame 43 along the third direction Z, the first wedge surface 421 can contact the second wedge surface 512, and apply force to the first rod end 5101 of the lock rod 51 using the wedge mating surface, so that the lock rod 51 can rotate around the second rotating shaft 53.

[0171] Combination Figure 7 , Figure 15 and Figure 17 When the linkage 42 of the first lock component 40 is in the first unlock position and the linkage 42 is not inserted into the first lock frame 43, the second lock component 50 is in the second lock position and the ratchet 511 of the lock rod 51 extends out of the first housing 10 through the first through hole 171.

[0172] Combination Figure 5 , Figure 6 , Figure 16 and Figure 18 When force is applied to the actuating member 41 of the first locking component 40, causing the linkage member 42 to insert into the first locking frame 43, the first wedge-shaped surface 421 of the linkage member 42 contacts the second wedge-shaped surface 512 of the locking rod member 51, and applies force to the second wedge-shaped surface 512 during the insertion into the first locking frame 43, causing the locking rod member 51 to rotate around the second rotating shaft 53. Figure 16As shown, when the locking lever 51 rotates clockwise, the ratchet 511 retracts from the first through hole 171 into the first housing 10 and compresses the elastic element 55, thereby placing the second locking component 50 in the second unlocked position.

[0173] When force is applied to the actuating member 41 of the first locking component 40, causing the linkage member 42 to disengage from the first locking frame 43, the force applied by the linkage member 42 to the second wedge-shaped surface 512 of the locking rod member 51 disappears. Under the action of the elastic member 55, the locking rod member 51 can rotate in the opposite direction. Figure 16 In the indicated direction, the locking rod 51 rotates counterclockwise, causing the ratchet 511 to extend out of the first through hole 171 and into the first housing 10, thereby placing the second locking component 50 in the second locked position.

[0174] The second rod end 5102 of the locking rod 51 of the second locking component 50 is exposed. In the scenario where the first enclosure 10 is not nested with the second enclosure 20, the user can apply force to the second rod end 5102 to make the locking rod 51 move so as to unlock the first enclosure 10 and the cabinet 2.

[0175] The specific structure of the lifting aid component 30 is described below.

[0176] Please refer to this as well. Figure 19 and Figure 20 , Figure 19 This is a partial enlarged view of the position of the lifting aid component on the side where the fourth box sidewall is located in the embodiment of this application. Figure 20 for Figure 19 The diagram shows an exploded view of the second housing and the lifting aid component. Figure 19 and Figure 20 The structure of the pull-out aid component 30 is clearly illustrated in the middle, but the first housing 10 is not shown.

[0177] In this embodiment, the pull-out assist component 30 includes a wrench 31, which is rotatably connected to the second housing 20. The wrench 31 includes a protruding arm 311, and the first housing 10 has a third through hole 173 (see...). Figure 9 The protruding arm 311 of the wrench 31 can extend from the third through hole 173 and cooperate with the limiting structure to generate a force applied to the second housing 20.

[0178] In one application scenario, the chassis 100 is not installed in the rack 2 of the server 1 and is in a relatively independent state. In this state, there is a need to perform plug-in / plug-out operations on the second enclosure 20. The chassis 100 can be equipped with a limiting fixture 60 to assist in the plug-in / plug-out operations of the second enclosure 20. The limiting fixture 60 is detachably connected to the first enclosure 10, and a limiting structure that cooperates with the wrench 31 is provided on the limiting fixture 60.

[0179] In a specific implementation, the limiting structure of the limiting fixture 60 is a limiting recess 61, which has a first limiting wall 611 and a second limiting wall 612.

[0180] The protruding arm 311 of the wrench 31 installed in the second housing 20 extends out of the third through hole 173 of the first housing 10 and can be inserted into the limiting recess 61 of the limiting fixture 60.

[0181] The operation of the pull-out component 30 will be explained below by referring to the insertion and removal of the second housing 20 relative to the first housing 10.

[0182] When the wrench 31 rotates relative to the second housing 20, the protruding arm 311 can move between the first limiting wall 611 and the second limiting wall 612, and is configured such that: when the wrench 31 rotates to the point where the protruding arm 311 abuts against the second limiting wall 612, a force along the insertion direction can be applied to the second housing 20, facilitating the insertion of the connector in the second housing 20 into the connector in the first housing 10; when the wrench 31 rotates to the point where the protruding arm 311 abuts against the first limiting wall 611, a force along the pull-out direction can be applied to the second housing 20, facilitating the disconnection of the connector in the second housing 20 from the connector in the first housing 10.

[0183] In the specific implementation, the rotation center line of the wrench 31 relative to the second housing 20 is parallel to the third direction Z, and the first limiting wall 611 and the second limiting wall 612 of the limiting recess 61 are arranged along the second direction Y.

[0184] The wrench 31 with protruding arms 311 can form a lever structure. The wrench 31 can have two protruding arms 311. According to the need for insertion and extraction, each protruding arm 311 can be inserted into the limiting recess 61 in sequence to generate sufficient insertion and extraction force. The two protruding arms 311 are the first protruding arm 3111 and the second protruding arm 3112.

[0185] exist Figure 19 and Figure 20From the perspective shown, when the wrench 31 rotates clockwise, the second protruding arm 3112 first inserts into the limiting recess 61, and the second protruding arm 3112 moves toward the second limiting wall 612 until it abuts against the second limiting wall 612. The force between the second protruding arm 3112 and the second limiting wall 612 can cause the second housing 20 to move toward the interior of the first housing 10 along the second direction Y. As the wrench 31 continues to rotate clockwise, the second protruding arm 3112 disengages from the limiting recess 61, and the first protruding arm 3111 re-inserts into the limiting recess 61. The first protruding arm 3111 inserts into the limiting recess 61 and moves toward the second limiting wall 612 until it abuts against the second limiting wall 612. The force between the first protruding arm 3111 and the second limiting wall 612 allows the second housing 20 to continue moving toward the interior of the first housing 10 along the second direction Y. Thus, through the relay cooperation of the second protruding arm 3112 and the first protruding arm 3111, the second housing 20 can be easily installed inside the first housing 10.

[0186] exist Figure 19 and Figure 20 From the perspective shown, when the wrench 31 rotates counterclockwise, the first protruding arm 3111 first inserts into the limiting recess 61, and the first protruding arm 3111 moves toward the first limiting wall 611 until it abuts against the first limiting wall 611. The force between the first protruding arm 3111 and the first limiting wall 611 can cause the second housing 20 to move toward the outside of the first housing 10 along the second direction Y. As the wrench 31 continues to rotate counterclockwise, the first protruding arm 3111 disengages from the limiting recess 61, and the second protruding arm 3112 re-inserts into the limiting recess 61. The second protruding arm 3112 is inserted into the limiting recess 61 and moves toward the first limiting wall 611 until it abuts against the first limiting wall 611. The force between the second protruding arm 3112 and the first limiting wall 611 allows the second housing 20 to continue moving toward the outside of the first housing 10 along the second direction Y. Thus, through the relay cooperation of the first protruding arm 3111 and the second protruding arm 3112, the second housing 20 can be easily pulled out of the first housing 10.

[0187] The above example illustrates the use of a wrench 31 with two protruding arms 311. In actual applications, a wrench 31 may have only one protruding arm 311. If space permits, the wrench 31 may also have more protruding arms 311. The operation process is similar to that described above and will not be repeated here.

[0188] The wrench 31 has a hinge hole 312, through which a pin 32 passes and is hinged to the second housing 20, so that the wrench 31 can rotate relative to the second housing 20 about the pin 32.

[0189] In some examples, the pull-out aid 30 includes two wrenches 31 arranged along the second direction Y, meaning that wrenches 31 are provided at both ends of the second housing 20 along the second direction Y. The pull-out aid 30 also includes a handle 33 extending along the second direction Y, connecting the two wrenches 31. Thus, the user can hold the handle 33 to rotate the two wrenches 31 synchronously, making operation convenient. When the two wrenches 31 are arranged along the second direction Y, the rotation directions of the two wrenches 31 are opposite during insertion and removal operations. Taking the insertion and removal of the second housing 20 relative to the first housing 10 as an example, combined with... Figure 4 When the second box 20 needs to be inserted into the first box 10, the wrench 31 of the pull-out aid 30 installed near the side wall 230 of the third box rotates counterclockwise, and the wrench 31 of the pull-out aid 30 installed near the side wall 240 of the fourth box rotates clockwise. When the second box 20 needs to be pulled out of the first box 10, the wrench 31 of the pull-out aid 30 installed near the side wall 230 of the third box rotates clockwise, and the wrench 31 of the pull-out aid 30 installed near the side wall 240 of the fourth box rotates counterclockwise.

[0190] In some examples, the pull-out aid 30 also includes a connecting shaft 34 and a locking member 35. The connecting shaft 34 extends along the second direction Y and is inserted into the handle 33. The locking member 35 is sleeved on the connecting shaft 34 and can be used to engage with the second housing 20 to limit the relative position of the handle 33 and the second housing 20 after the second housing 20 is inserted into the first housing 10. This configuration can prevent accidental operation that would cause the handle 33 to rotate the wrench 31 or the second housing 20 to disengage from the first housing 10 due to the reaction force of the connector when the second housing 20 does not need to be pulled out.

[0191] like Figure 19 and Figure 20 As shown, the pull-out aid 30 is in the state where the second housing 20 has been installed in the first housing 10. The handle 33 is close to the fifth side wall 250 of the second housing 20. A snap-fit ​​structure that cooperates with the snap-fit ​​member 35 can be provided on the fifth side wall 250. After the handle 33 drives the wrench 31 to rotate to the state where the first protruding arm 3111 abuts against the second limiting wall 612, the snap-fit ​​member 35 of the handle 33 can snap into the fifth side wall 250.

[0192] In a specific implementation, a torsion spring 36 can be provided between the buckle 35 and the handle 33. The torsion spring 36 can be sleeved on the connecting shaft 34. One arm of the torsion spring 36 abuts against the handle 33, and the other arm of the torsion spring 36 abuts against the buckle 35. The torsion spring 36 is configured to keep the buckle 35 in a snap-fit ​​state with the second housing 20.

[0193] The latching member 35 may be provided with a pressing part. The user can apply force to the latching member 35 through the pressing part, so that the latching member 35 rotates around the connecting shaft 34 to overcome the elastic force of the torsion spring 36, thereby disengaging the latching member 35 from the second housing 20, releasing the limit between the handle 33 and the second housing 20, and making it convenient to rotate the wrench 31 to pull out the second housing 20.

[0194] In some examples, the limiting fixture 60 can be a plate-like structure, and the limiting fixture 60 can be detachably connected to the first housing 10 by fasteners such as screws. Combined with... Figure 10 , Figure 19 and Figure 20 The first housing 10 is provided with a second mounting hole 182, and the limiting fixture 60 is provided with a fixing hole 62 that matches the position of the second mounting hole 182. The limiting fixture 60 and the first housing 10 are connected by fasteners passing through the fixing hole 62 and the second mounting hole 182.

[0195] The limiting fixture 60 is connected to the outside of the first box side wall 130 or the second box side wall 140 of the first box body 10. When the pull-out component 30 is provided with two wrenches 31, the limiting fixture 60 that cooperates with the two wrenches 31 can be an integral structural component, which can simplify the number of parts and facilitate assembly.

[0196] Combined Figure 3 , Figure 4 and Figure 11 The limiting fixture 60 can also be fixed to the mounting base 52 of the second locking component 50 at the same time. The mounting base 52 is provided with a fourth connecting hole 522 that matches the second mounting hole 182 and the fixing hole 62.

[0197] In another application scenario, the chassis 100 is installed inside the rack 2 of the server 1. In this scenario, the aforementioned limiting fixture 60 is not installed on the first housing 10 of the chassis 100. The limiting structure that cooperates with the protruding arm 311 of the wrench 31 of the pull-out component 30 is provided on the rack wall of the rack 2. A limiting groove extending along the second direction Y can be provided on the rack wall of the rack 2. The limiting groove has two groove sidewalls arranged along the second direction Y. The protruding arm 311 of the wrench 31 extends out from the third through hole 173 of the first housing 10 and is inserted into the limiting groove of the rack 2. When the wrench 31 is rotated, the force is applied to the second housing 20 by the abutment between the protruding arm 311 and the groove sidewall of the limiting groove.

[0198] The above Figures 1 to 20 In the embodiment where server node 3 is the main focus, the second enclosure 20 is positioned close to the bottom wall 120 of the first enclosure 10. In other embodiments, the second enclosure 20 may also be positioned close to the top wall 110 of the first enclosure 10. The relevant structural arrangements can be adapted and will not be described again here.

[0199] This application also provides a server, which includes a rack and the server node described in the foregoing embodiments, and the server node can be installed in the rack.

[0200] It should be understood that other functions of the server are not the core inventive points of this application, and can be implemented by those skilled in the art based on conventional technology, so they will not be described in detail here.

[0201] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
